This paper describes an innovative technique far the quality control of gear pumps based on the frequency analysis of the oscillations of the discharge pressure using a new mathematical tool called "the spectrum of the power cepstrum." It consists in applying Fourier transform of the presRure data sampled in the time domain three times consecutively. The innovative technique makes it possible to obtain an acceptance mask far a set of gear pumps in the same series, in which the class and entity of a defect can be detected.

Abstract

This paper describes an innovative technique far the quality control of gear pumps based on the frequency analysis of the oscillations of the discharge pressure using a new mathematical tool called "the spectrum of the power cepstrum." It consists in applying Fourier transform of the presRure data sampled in the time domain three times consecutively. The innovative technique makes it possible to obtain an acceptance mask far a set of gear pumps in the same series, in which the class and entity of a defect can be detected.
